Attributes Price Increases

[RyanSmith]

Hello,

 

I'm writing some custom code to create a new attribute system that pulls its values out of a new database table. I have it working pretty well, however I can't get the price to increment when they select the new attribute. Does anyone know how this code works? Could someone explain it to me so I can figure out what I'm doing wrong.

 

Thanks

a little more info might help.

Some code?

 

Are you using just = or += to assign values

Thanks for your reply. I figured it out. I'm adding a dollar to any product using the new attribute system. If anyone would like to see where I edited the code here it is.
